Neil Fleet Posted November 2, 2016 Report Share Posted November 2, 2016 Hi All I was wondering if someone could help me with a programming issue. I am relatively new to PLC programming and am struggling with how to send a one shot analogue output based on a digital input signal. Is it as simple as controlling a relay and running the analogue output through the volt free contact or can I do it in the PLC. thanks in advance.

You will need to have a thorough understanding of the electronics involved (rise and fall times, etc). If you just need a certain voltage or current output for a short period of time, use the analog output or a relay attached to a digital output and run a timer in the PLC triggered by your input. There is a very convenient "Extended Pulse" timer you can use. Quote Link to comment Share on other sites More sharing options...
